First of all: A big thank you to everyone contributing to this thread. I successfully flashed V4 on my BenQ XL2420z.

I always had a BenQ XL2420z with the first firmware version. Back in the day BenQ agreed to flash V2 for me if I send the monitor to their HQ. When it came back it had V2 installed but the OSD/Menu was unreadable. So they retook it and gave me back one with V1. I gave up on V2 after this.

Fast forward today and I somehow stumbled across Blur Busters again and read about the DIY Linux method. Searched for a VGA cable, took out my trusted Lenovo X300 and went to town. Followed everything in the guide until this occured:

Assuming XL2411 v7 is simply the Zowie rebrand of the XL2411Z, and might be the same as V5.At least for the XL2720Z, the v7 firmware is just the zowie rebrand, and I saw no differences whatsoever between the XL2720Z V5 and XL2720 V7, besides the logo.

I don't 'have access to any firmwares anymore besides the old ones available like XL2420Z/XL2411Z V4, and XL2720Z V5. I only got XL2720 V7 because some really nice person here was kind enough to dump it with Linux.

I haven't seen anyone willing to dump firmwares of any monitors since that time. The last attempted dump of anything was Strobemaster dumping his XL2730Z firmware with the RT809F ISP device, but he said he got a verify error after dumping it (he had to use the HDMI connection), so it's unknown whether that dump was good or if it would cause a brick.

And no one knows if flashrom can dump or flash the new realtek 2796BF firmwares either.

I'm surprised no one has even tried. Maybe people don't care. Or maybe they're just afraid of bricking something. But just reading firmwares won't brick anything.

Ok so let me ask this again since I asked a long time ago but got NO replies...like, literally no one even trying:

Has ANYONE been willing or tried to adopt the flashrom method of dumping the old Benq firmwares (NOT FLASHING THEM, just identifying the i2c address and making a backup only), to any of the newer Realtek 2796BF monitors? Does anyone know if these monitors even use Macronix flash chips anymore?

Referring specifically to the XL2735, XL2540, XL2546 and any newer monitors using this scaler/chipset ?Of course, the chip identifier string must be known, and flashrom must also support the new scaler/firmware/flash chip as well, since it's not MX25L1606E anymore.

Hello Guys!I have the problem that i can't download flashrom from the svn co svn:// and the coreboot link.It says that i can't connect to the host because the connection is declined.Can someone post an alternative Link or help me with this problem?

I have a xl2411 zowie "rebrand" and it has v5, does this mean that the v7 firmware is not just the zowie rebrand?

I'll clean it up a bit soon, but currently, you might have to modify one line to match your I2C device : line 73 of mstarddc_spi.c, the "/dev/i2c-1" device has to match the one corresponding to your VGA port (you get this info using "i2cdetect -l").

Got zowie 2536 since idk what flashchip its use its have v3 firmware once i get flashrom complied in linux i check. If chip have realtek then flashrom dosent support it i did dump on my 2411z might i do on 2536 also if flashrom eats that chip.

editits use unknown martonix chip this takes for while until i can dump it ic bus communicates with flash but flashrom cant dump on unknown chips.

Yo not get communication with DP DVI did work on me

You can get latest flashrom and use make command that its complie everything you get that command on flashrom site witch complies with mstar so make without extra command not complie mstar support

Mstar is supported newest flashroms only you have to complie with extra command that adds support to flashrom

no need to mess patches and outdated infos

EDIT2

Sent to flashrom devs log to support that flash if i get support from flashrom to support that chip we get dump. Easy as that.

I have an xl2720z rev 2 and displayport cable problems where the monitor doesn't get a signal after waking up, and this morning just booting up. I understand V4 firmware solves this, but I have followed the links in this thread and they're all down or gone.

Is there a current V4 firmware file for the 2720Z, along with some instructions that don't look like you need to work for nasa?

Thanks in advance for your time; my apologies if I missed a post.

I have the current V7 firmware for the XL2720Z.I found no difference between the V7 "Zowie" firmware over the V5 "Benq" firmware besides the logo change.

That link gets you the rt809f and all the adapters, but all you need is the VGA cable for the Benq. You still have to find the english verison of the software though (used to have the link, check the blurbusters search to see if it's still posted, I don't remember it anymore, but can google "Rt809f english software".

Chief had the Mstar ISP software hosted on blurbusters. If it's not there, send Chief a message.

@Chief do you stiill have the ISP software?

Thanks for the reply and current links Falkentyne.

Currently have a buddy trying to sort through this linux stuff and see if it can be done with a rasberry pi? Going to give that a shot first... but my main problem with that method is searching for the right i2c bus. It's all Greek to me, which is why building/buying a tool seems like the safer option.

I grabbed all the mstarl software and V5 firmware. Do you know if the Mstar install software would work with the RT809F-Programmer or would that require some other software? Or should I just grab the mstar device if we can't figure out/aren't comfortable with trying Linux?
